Elimination of misfolded proteins is crucial for proteostasis and to prevent proteinopathies. Nedd4/Rsp5 emerged as a major E3-ligase involved in multiple quality control pathways that target misfolded plasma membrane proteins, aggregated polypeptides and cytosolic heat-induced misfolded proteins for degradation. It remained unclear how in one case cytosolic heat-induced Rsp5 substrates are des...

For radical designs the hot-carrier reliability is an important issue. This creates the need for the numerical simulation of hot-carrier induced degradation. From a design point of view, the goal of the degradation simulation will be the hot-carrier aging simulation for the prediction of device lifetime. This simulation requires a complicated set of physical models, which includes the hot-carri...

an hplc method for determination of mebeverine hydrochloride (mh) in the presence of its degradation products was developed. the degradation of mh was studied under hydrolysis, oxidative and photolysis stress conditions. under alkaline, acidic and oxidative conditions, degradation of mh was observed. the separation was performed using a symmetry c 18 column and a mixture of 50 mm kh 2 po 4 , ac...

In eukaryotic cells, the ubiquitin/proteasome system (UPS) is a key determinant of proteostasis as it regulates the turnover of damaged proteins. However, it is still unclear how the UPS integrates intrinsic and environmental challenges to promote organismal development and survival. Here, we set up an in vivo degradation assay to facilitate the genetic identification of ubiquitin-dependent pro...

The degradation behavior of cefixime trihydrate was investigated under different stress conditions of acidic hydrolysis, alkaline hydrolysis and oxidation using spectrophotometry. Stability indicating spectrophotometric methods were developed that could separate the drug from its degradation products formed under these stress conditions. The UV spectral characteristics of the drug and degraded ...

An overview of evolution of transistor parameters under negative bias temperature instability stress conditions commonly observed in p-MOSFETs in recent technologies is presented. The physical mechanisms of the degradation as well as the different defects involved have been discussed according to a systematic set of experiments with different stress conditions. According to our findings, a phys...

The general stress response of yeast involves the induction of approximately 200 genes in response to any one of several stresses. These genes are activated by Msn2 and repressed by the Srb10 kinase, a member of the mediator complex. Normally, Msn2 is exported from the nucleus, and Srb10 represses STRE gene expression. Under stress, Msn2 relocalizes to the nucleus and, with the relief of Srb10 ...

TiO2 is used in many sectors of industry such as health, food, defense, and energy. It a well-known fact that especially applications the field organic hybrid solar cells (OHSC) an electron transfer layer energy sector. However, OHSCs have degradation problem because atmospheric stress factors laboratory atmosphere, prolonged light application (light soaking), UV light. To understand meta/insta...
